This patch adds supports for Accelerated Receive Flow Steering. When the desired rx is different from current rq, for a flow, kernel calls the driver function enic_rx_flow_steer(). enic_rx_flow_steer adds a IP-TCP/UDP hardware filter. Driver registers a timer function enic_flow_may_expire. This function is called every HZ/4 seconds. In this function we check if the added filter has expired by calling rps_may_expire_flow(). If the flow has expired, it removes the hw filter. As of now adaptor supports only IPv4 - TCP/UDP filters. Signed-off-by: Govindarajulu Varadarajan <_govind@gmx.com> Signed-off-by: David S.
